I have just received this Walkman via a legacy. Came with the power plug and carrying case but not the strap. Have some cassettes too. Apparently only used for a few months and sitting in a closet for at least twenty-five plus years. It's in great condition (leather case too).
I still have some cassettes which I recorded off the airwaves, oops! Put some batteries in and guess what, worked first time. Put an Earth Wind and Fire album in and connected to my system to use as a tape deck. You know, the top end may not be all there, compared to digital, but love the sound of EWF after all these years.
If anyone wants to see photos, will upload.
Surely a great piece of kit, even after all this time. They don't make kit like this anymore.
All the manuals, info etc., still on the net. Great stuff.
Kind regards and happy listening.

Tad.
